Dahl Process

ABSTRACT

The Dahl mining system is an environmentally safe, chemical free system that mines microscopic precious metals from head ore adding water and urea agitating this mixture until the precious metals are released from the head ore. Polymers are then added to the mixture and agitated until the polymers reach full hydration. The polymers are then screened from the mixture for the dehydration process. The extraction portion of this process begins by separating the metals from the polymers or bar in a controlled environment or room.

FIELD OF THE INVENTION

The present invention generally relates to the Dahl Process. The Dahl Process is a process of microscopic mining of precious metals such as gold, silver and platinum using the method of adding environmentally friendly products, thus there is no contamination of the soil.

BACKGROUND OF THE INVENTION

Current mining systems use contaminates to leach or penetrate the soil for release of these precious metals. It is a concern that leaching may affect natural aquifers contaminating natural sources of water. The Dahl Process eliminates leaching using only safe, natural resources for this release of precious metals from soil thus protecting the soil and water sources located in the specified mining location. In platinum mining, current techniques are used such as dynamite blasting to separate the ore from the heavy metals. The Dahl Process uses an agitation method to release these heavy metals maintaining the integrity of the heavy metals plus the softer metals which may blow off or dissolve during other current mining processes, thus; retaining a higher yield of precious metals. Smelting is a common practice among mining processes. If a heavier metal is desired, the high temperature that is required to retrieve this metal melts and dissolves the softer metals such as gold and silver. The Dahl Process is able to extract the heavy metal without dissolving the more soluble metals thus, yielding a higher amount of precious metals as these metals are absorbed by polymers. Tests have concluded these metals are in fact being absorbed and retained by the polymers.

BRIEF SUMMARY OF THE INVENTION

Accordingly, the present invention or the Dahl Process provides a microscopic mining system that is both friendly to the environment and allows the mining of microscopic metals that would otherwise be lost during the current mining processes. The first step in this microscopic mining process respectively is to take the excavated head ore from the property which is being excavated and size it down to a predetermined size so that the mining process may begin. A predetermined amount of water shall be added to this head ore and placed in a mixture to be agitated. A predetermined amount of Urea or any similar product shall then be added to the mixture and agitated once again. This mixture must be agitated until the precious metals are then released from the head ore. Polymers are then added to the head ore and precious metal mixture and then agitated until the polymers reach maximum hydration. The polymers are then screened from the solution for dehydration. Dehydration must be in a strictly controlled environment and must not exceed a temperature determined by the inventor. The extraction process now begins adding the dehydrated polymers, and the “flux” which is a mixture consisting of environmentally friendly products such as silver chloride, soda ash, and borax glass adding or subtracting to this flux accordingly what the inventor may see fit to a mixer and mix thoroughly. For heat, place this mixture in a container and cover with a lid. Heat the container, raising the heat very slowly until the heat reaches a predetermined temperature. Maintain this temperature until the precious metals accumulate at the bottom of the container, at which time pour the mixture into a trough to expose the accumulated bar of precious metals at the bottom of the container. If the extraction process excludes heating, the polymers shall be taken to a controlled environment where the precious metals shall be extracted from the polymers.

BRIEF DESCRIPTION OF THE DRAWINGS

The above and additional features and advantages will become more readily apparent from the following detailed description of the invention taken in conjunction with the drawings in which:

FIG. 1 is a schematic diagram depicting the basic system of the present invention.

Referring now to FIG. 1, there is shown the environmentally friendly microscopic mining process. Head Ore 1 shall be excavated from the appropriate mining location and sized down 2 to the pre-determined sample size 3 to begin the mining process. The appropriate amount of water shall be added 4 to the sample to begin the mixture and agitation process 5 leaving a well agitated sample mixture 6. Urea is then added to the sample 7 and the agitation process 8 begins again. As the sample mixes, the precious metals 9 begin to release from the head ore mixture. Polymers are then added 10 to the mixture of head ore and precious metals. The agitation process begins again 11 at which time the polymers reach full hydration absorbing the precious metals. The polymers are then screened 12 separating the polymers from the head ore mixture. The polymers are then left out for complete dehydration. The heating process begins. The dehydrated polymers, pre-determined amounts of soda ash, silver chloride and borax glass are added to a container used for heating 13 and mixed thoroughly. The container is then heated, raising the temperature very slowly. When the heated sample mixture reaches a predetermined temperature the precious metals begin to accumulate at the bottom of the container 14 in the form of bars. This process salvages specifically gold, silver and platinum where most processes heat at a high temperature burning off the gold and silver in order to obtain the platinum. The bars are taken to a controlled environment or room 15 where acids 17 are used to separate the metals from each other. If the extraction of the precious metals from the polymers does not require smelting, the dehydrated polymers are taken to a controlled environment or room 16 where the acids 17 are then used to separate the metals from the polymers. Since this takes place in a controlled environment, there is no contamination of natural resources during the Dahl process and this process yields higher claims of each precious metal from the ore. 

I claim:
 1. A method of an environmentally safe mining process through extraction of microscopic precious metals for the head ore comprising: (a) releasing said microscopic precious metals by introducing water and nitrogen based fertilizer into said head ore while agitating the mixture; (b) introduce the polymers to said mixture and allow said polymers to absorb said precious metals while said agitation process continues; (c) screen said polymers from said mixture and allow complete dehydration of said polymers; (d) extraction of said precious metals from said dehydrated polymers now occurs in a controlled setting or room where said precious metals are separated from said dehydrated polymers with the use of chemicals which shall never be introduced into the environment.
